High voltage eletricity transmission lines, Portugal


<div class="horipane"><div class="title active">Description</div><div class="content"><table class="table"><tbody><tr><td class="fld"></td><td class="columns"><div class="less">High-voltage power lines, also called transmission lines, are those whose nominal voltage is greater than or equal to 60 kV. These lines connect electric generation plants (thermal, hydro and wind power plants) to substations or between several substations. They are usually aerial, but can be run underground. In Portugal, the construction of a number of these structures was planned in various parts of the country by the National Power Network (REN) and led to protests of local people and the creation of a National Civic Movement Against High-Voltage Power Lines. Communities are concerned because a number of studies suggest the increase of leukemia cases in children, higher risk of brain tumors and the frequency of stress cases and depression due to low frequency noise from high-power lines.</div><a class="seemore" href="#">See more...</a><div class="more" style="display:none">In 2005, there was the public consultation from the Environmental Impact Assessment-EIA of a high-voltage line of 220 kV, designed by REN to connect the Alto Mira substation, in Amadora, to the Trajouce substation in the municipality of Cascais, crossing the municipality of Sintra. The most affected county would be the municipality of Sintra, receiving the installation of 27 out of 30 electricity towers, which in some cases would be located 25 meters from houses. Only on the last day of the public consultation and due to the mobilization of the Environmental Association Olho Vivo, did local people become aware of the project. The local Civic Movement criticized the lack of public participation in the public consultation and asked for the line to be buried underground. The movement started a petition and collected more than 5 thousand signatures. In 2006, the State Environment Secretary, in the environmental impact statement of the project, argued against the placement of towers in the archaeological area of Alto Colaride. <br/><br/>In August, Quercus and Olho Vivo announced a legal process against the Portuguese State for non-fulfillment of the directives concerning the very high-voltage line present in the environmental impact assessment and for not making alternative studies, as required by European legislation. In March 2007, about 100 people protested in Sintra. A public petition was approved unanimously by the Parliament Commission of the local Government. Members announced the formation of a working group with representatives from all parties to follow up on the issue. The operation of the line was temporarily suspended but restarted later. In December, an agreement between REN and the City Council of Sintra was established so that part of the line was to be buried. This operation, supported by the local authority, started in March 2008.<br/><br/>These events occurred in parallel and together with similar conflicts in other places across the country. In April 2007 there was a meeting of several national civic movements against power lines and the National Movement Against High-Voltage Lines in Urban Areas was created. In August, after the planning and approval of the installation of the very high-voltage line between Tunes-Estoi route, crossing the municipalities of Silves, Albufeira, Loulé and São Brás de Alportel, the Neighborhood Association of the population from Vale Fuzeiros (Silves) began to actively question the installation of this line and the route chosen, demanding the lines' displacement to the north as an alternative solution. A petition addressed to the parliamentary group Portuguese Communist Party-PCP collected more than 300 signatures a detailed report on the case was presented, claiming that the proposed route was very close to housing and would, therefore, affect ecological areas, organic farms and tourism projects, endangering local archaeological heritage. REN announced that the route would be changed in order to safeguard existing archaeological remains in Vale Fuzeiros, but the population did not accept this concession. In October, a vigil and hunger strike was organized near the São Bento Palace, in Lisbon, by the National Movement Against the Power Lines initiated by Sintra and Silves residents. Further studies were carried out and new paths were proposed, but the population continued to protest and REN paralyzed the construction of the new high-voltage line Tunes-Estoi in the valley. The Silves population celebrated this "desistence", but part of the line already built in Tunes-Estoi caused problems in other lines, such as in Alcalar and Poio, connecting the wind power of Espinhaço de Cão (Lagos) and Porto de Lagos (Portimão), and in the section of Albufeira substation. Facing mass protests, the City Council and Energies Distribution of Portugal-EDP signed an agreement to run the high-power lines underground.<br/><br/>The Power line Foz Tua-Amamar, which crosses an area in the Alto Douro Vinhateiro, Region classified as world heritage by the UNESCO, together with the Foz Tua dam, was also challenged by the Platform Save Tua. In April 2012, the Ministry of Environment through the Environmental Impact Statement gave an unfavorable opinion to the line installation because this would have significant socio-economic impacts in terms of land use, landscape and conservation of cultural heritage of humanity. In a joint press statement , environmental associations such as LPN, GEOTA, FAPAS and Association of Friend of Vale do Tua River, expressed their support to the Ministry of Environment's decision reinforcing the idea of the poor design of the Foz Tua dam project. The EDP announced that it would explore alternatives, which included the need to bury the line, which the associations have described as an attempt to camouflage the negative impacts.<br/><br/><a class="seeless" href="#">(See less)</a></div></td></tr></tbody></table></div></div><div class="horipane"><div class="title active">Basic Data</div><div class="content"><table class="table"><tbody><tr><td class="fld">Name</td><td> High voltage eletricity transmission lines, Portugal</td></tr><tr><td class="fld">Country</td><td><a href="/country/portugal">Portugal</a></td></tr><tr><td class="fld">Site</td><td>Sintra, Silves, Foz Tua, Albufeira, Portimão</td></tr><tr><td class="fld">Accuracy of Location</td><td>LOW country/state level</td></tr></tbody></table></div></div><div class="horipane"><div class="title active">Source of Conflict</div><div class="content"><table class="table"><tbody><tr><td class="fld">Type of Conflict (1st level)</td><td>Infrastructure and Built Environment</td></tr><tr><td class="fld">Type of Conflict (2nd level)</td><td>Transport infrastructure networks (roads, railways, hydroways, canals and pipelines)</td></tr><tr><td class="fld">Specific Commodities</td><td><a href='/commodity/land'>Land</a><br /><a href='/commodity/electricity'>Electricity</a></td></tr></tbody></table></div></div><div class="horipane"><div class="title active">Project Details and Actors</div><div class="content"><table class="table"><tbody><tr><td class="fld">Project Details</td><td class="columns"><div class="less">The high-voltage line Fanhões-Trajouce has over 40 km and runs at 220 kV.
